The Bluetooth function allows you to pair the Garmin nüvi 660 with my Sony Ericsson mobile phone and should provide a voice operated hands free kit. I had no problem pairing the device with my Sony Ericsson K800i phone. Once paired I had access to my phone book, call lists phoning out and receiving calls via sat nav unit but still can not achieve voice dialing. What is the solution ?
